SPECIFICATION forming part of Letters Patent No. 743,171, dated November 3, 1903. Application filed March 7, 1903. Serial No. 146,655. (No model.)

To a whom it may concern:

Be it known that I, WALTER GRANT J AMIE- soN, a citizen of the United States, residing at Union Hill, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Vessels, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to sailing vessels, steam and other vessels; and the object thereof is to provide improved means for reducing the friction occasioned by a vessel passing through the water; andwith this and other objects in view the invention consists in the construction and combination of parts hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which- Figure 1 is a side View of the front end of a vessel provided with my improvement and partially in section; Fig. 2, a side view of the front end of a vessel provided with my improvement and showing a modification, and Fig. 3 a section on the line 3 3 of Fig. 2.

In the drawings forming part of this specilication I have shown at a, the front end of the hull of a vessel, and the water-line is indicated at b, and in the practice of my invention, as shown in Fig. 1, I secure in the hull of the vessel and slightly below the water-line a tube 0, the front end of which opens forwardly through the hull, as shown at 0 and below the water-line, and the other end of which extends backwardly any predetermined distance and opens downwardly through the hull at any desired point, as shown at 0 and below the water-line. In this form of construction I also place in the side of the hull tubes,which open outwardly above the water-line, as shown at d, and which extend downwardly and backwardly and open below the water-line and through the side of the hull at any desired point, as shown at 01 The tube 0 serves to reduce the pressure of water when it strikes the bow of the vessel and to reduce friction, and said tube also serves to hold the vessel steady and to prevent the efiects of the thumping and beating of the Water on the bow, and said tube being larger at its rear than at its front end the passage of water therethrough is facilitated. The tubes (1, which emerge above the waterline at their front ends, serve for the same purpose in a small sailing vessel or in a larger vessel when said vessel is close-hauled or keeled over, as frequently occurs, and any desired number of these tubes may be employed.

In Figs. 2 and 3 I have shown a modification in which a tube c is secured in the front of the hull below the water-line and is provided with two branches 6*, which extend backwardly and outwardly and open outwardly through the opposite sides of the hull, as shown at 6 and these tubes are also larger at their rear ends than at their front ends, and the operation of this form of construction will be similar to that of the tube or tubes 0 in the construction shown in Fig. 1.

In Fig. 1 it will be observed that the tube 0 opens outwardly at the front through the cut-water of the hull and downwardly and backwardly through the keel portion of the hull, while in the construction shown in Figs. 2 and 3 the tubes e open forwardly through the out water and downwardly and backwardly through the sides of the hull above the keel portion thereof, and with either form of construction the tubes referred to will operate to produce practically the same results, and the tubes (1 (shown in Fig. 1) may also be employed in connection with the construction shown in Figs. 2 and 3.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A vessel the hull of which is provided at the bow with a tube which is located longitudinally therein and the front end of which opens outwardly and forwardly through the cut-water below the water-line, and the rear end of which opens downwardly and backwardly through the bottom portion of the hull at the bow end thereof, substantially as shown and described.

2. A vessel the hull of which is provided at the bow with a tube which is located longitu- IOU dinally therein and the front end of'which opens outwardly and forwardly through the cut-water below the water-line, and the rear end of which opens downwardly and backwardly through the bottom portion of the hull at the bow end thereof, the bow of the vessel being also provided in the opposite sides thereof above the Water-line with tubes which open outwardly and forwardly and which converge downwardly and backwardly and open backwardly and outwardly below the Waterline, substantially as shown and described.

3. A vessel the bow of which is provided with a plurality of tubes which are located in the side portions thereof rearwardly of the cut-water and which converge and open out-
